The 'master' branch should work for 3.9 and 3.10 The 'gr-3.7' and 'gr-3.8' branches are historical branch for those specific versions of But I haven't personally tested with 3.10.4 ... Doing CL / GL in multithread application always requires quite a bit of care and it's possible a recent version of GR broke one of the assumption made ... Cheers, Sylvain
